Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a submarine cable protection structure,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a submarine cable protection structure using a waste tire, and more particularly, to an undersea cable protection structure that can effectively protect an undersea cable from an anchor, a barbed wire and a fishing gear using a waste tire.

In general, submarine cables refer to cables installed on the seabed for power and communication between two isolated points, such as the continent, the continent, the land, and the islands.

With the rapid growth of the offshore wind power market and the increasing demand for construction of submarine cables such as power grid network projects between countries, there is an increasing trend in the world. Under the circumstances of domestic fishing activities and the anchors, The cable is liable to be damaged, and may be damaged by natural phenomena such as sea currents and waves due to sea currents, friction with the seabed. Here, the term beech horse refers to a horsehair of a metal material, and a horsehair refers to a pillar with a sharp cut end. The horsehair is put mainly in a farm, and it is hung horizontally on a horsehair to produce seaweeds such as kimchi and seaweed. This situation not only increases the cost of replacing and repairing the submarine cable, but also causes inconvenience to the public and damage to the industry due to the power supply interruption in the urban area.

To prevent this, an external cable is recently used or a protective duct is installed around the cable. Korean Patent Publication No. 10-0773953 is an invention relating to a duct for protecting a submarine cable, and is an invention relating to a duct for protecting a submarine cable that can prevent breakage of an anchor, a spike, and a fishing gear of a ship falling into the sea floor. Reference will now be made to Figs. 1 and 2 to describe the above-described prior art in detail. FIG. 1 is a view showing an anchor of a ship touching a submarine cable, and FIG. 2 is a view showing a duct construction method for protecting a submarine cable from an anchor or a fishing port. The anchor 5 is a mechanism used when the ship 4 is anchored in the sea 1 and anchors 5 attached to the vessel 4 are fixed to the sea bed 2 to anchor the vessel 4. The anchor 5 is lowered while the vessel 4 is anchored and the submarine cable 3 attached to the sea bed 2 is damaged by the anchor 5 in the course of the anchoring. This causes inconvenience to the public and industrial damage due to interruption of electric power supply, and the replacement and repair cost of the submarine cable 3 is increased. In addition, the submarine cable (3) may be damaged by fishing gear in the course of fishing activities.

In order to prevent the undersea cable 3 from being damaged, conventionally, a duct 6 for protecting the undersea cable was installed in such a manner as to cover the undersea cable 3. However, in the conventional construction method, there is a problem in that installation of the duct 6 is expensive and installation time is long. Further, when the cross-sectional area of the duct 6 is reduced in order to reduce the cost, there is a problem that the possibility of damaging the submarine cable 3 from the anchor 5, horseshoe or fishing gear of the ship is increased.

Another conventional technique for preventing the undersea cable 3 from damaging is a Rock-berm method in which a protective cover is formed by filling a stone around the submarine cable 3, but still the submarine cable 3 3) is broken.

To solve these problems, a submarine cable protection structure with cost reduction and safety is required.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a submarine cable protection structure using a waste tire, and more particularly, to a submarine cable protection structure using waste tires effectively protecting the submarine cables from anchors,

In order to achieve the above object, a submarine cable protection structure using waste tires is provided to extend along the longitudinal direction of a submarine cable so as to surround an outer circumferential surface of a submarine cable laid on a seabed and extended in one direction, And a plurality of fixing members extending along the longitudinal direction of the submarine cable so as to surround at least a part of the plurality of waste tires having the elastic material and the waste tire has elastic material, Thereby protecting the cable.

In addition, a plurality of fixing members of the submarine cable protection structure using the waste tire are characterized in that the unit volume weight is heavier than the plurality of waste tires. A plurality of waste tires are fixed by a plurality of fixing members, Is prevented.

Further, a plurality of waste tires of the submarine cable protection structure using waste tires are each connected through a chain.

The chain of the submarine cable protection structure using the waste tire is characterized in that the chains are repeatedly passed in a zigzag fashion up and down with reference to the holes formed in the plurality of waste tires to connect the plurality of waste tires.

Further, a plurality of waste tires of the submarine cable protection structure using the waste tire are inserted into the net, and a mattress is formed by the plurality of waste tires and the net.

Further, a plurality of waste tires of a submarine cable protection structure using waste tires are stacked in a vertical direction with reference to a submarine cable.

The plurality of fixing members of the submarine cable protection structure using the waste tire are characterized by being stone or waste concrete.

The submarine cable protection structure using the waste tire according to the present invention can effectively protect the submarine cable from the anchor, the horseshoe and the fishing gear of the ship due to the large ductility and the small rebound hardness of the waste tire.

In addition, since the cross-sectional area is smaller than that of the conventional duct construction method, the construction cost and time are reduced.

In addition, there is an advantage that waste tires can be covered with stone or waste concrete to prevent the loss of tires due to waves or tides due to light weight of waste tires.

3 is a perspective view illustrating a protection structure of a submarine cable using a waste tire according to the present invention. Hereinafter, a structure for protecting the submarine cable according to the present invention will be described with reference to FIG.

First, a submarine cable 300 is extended and installed in the sea floor 200 of the sea 100 in one direction. A plurality of waste tires 400 are disposed to surround the outer circumferential surface of the submarine cable 300 exposed to the seabed 200. At this time, a plurality of waste tires 400 are disposed along the longitudinal direction of the submarine cable 300. The number of the waste tires 400 is not limited, and the methods 410, 420 of the plurality of waste tires 400 will be described later. A plurality of fixing members 500 are disposed so as to enclose a plurality of waste tires 400 in such a manner as to cover at least a part or the entirety of the plurality of waste tires 400. In this case, (300) in the longitudinal direction of the submarine cable (300).

The tire refers to a rubber that is fitted around the outer periphery of a wheel of a vehicle such as an automobile, and a tire whose lifetime has expired is referred to as a waste tire 400. The waste tire 400 generally has a low recycling frequency. However, if the waste tire 400 is used to protect the submarine cable 300, unlike the conventional duct construction method, it is possible to reduce the cost of raw materials and reduce environmental pollution occurring in the process of treating the waste tire 400 . In addition, there is also an advantage in that it can respond to the eco-friendly policies of the Korean government, since the material can be secured almost free of charge, and material costs are scarcely generated and materials to be disposed of are used.

The waste tire 400 is a main component of rubber, and the rubber is typically a material having an elastic material. Due to the characteristics of materials having such elasticity, waste tires have a high ductility and a low rebound hardness. The ductility refers to a property of giving a tensile force to a material to cause a plastic deformation to be drawn in a linear shape. The larger the ductility, the more the impact from the outside is absorbed. The rebound hardness means that the object is collided with the test piece to show a large or small jump. The lower the rebound hardness, the more the impact from the outside is absorbed. The waste tire 400 has a high ductility and a low rebound hardness as compared with a metal material used in a conventional duct or the like. Accordingly, when an anchor, a barbed horse and a fish from the ship reach the vicinity of the submarine cable 300 and come into contact with the waste tire 400 according to the present invention, they more effectively absorb the impacts from the anchor, do. That is, if the submarine cable 300 is installed to protect the submarine cable 300 through the waste tire 400 according to the present invention, the submarine cable 300 can be more stably protected than the conventional duct construction method. In addition, since the rebound strength and ductility are excellent, even if the thickness is maintained, the shock can be absorbed and the submarine cable 300 can be efficiently protected without taking up a large volume.

When the submarine cable 300 is attached to the seabed 200, the remainder is exposed to the seabed 200 except for the portion embedded in the seabed 200. At this time, the plurality of waste tires 400 surround the outer circumferential surface portion of the submarine cable 300 exposed to the seabed 200. There is no limitation on the manner in which the plurality of waste tires 400 wrap the submarine cable 300. However, in a preferred embodiment, the length of the submarine cable 300 is set so that the plurality of waste tires 400 covers the submarine cable 300, So that a plurality of disposed tires 400 arranged in a rectangular shape in the width direction extend along the longitudinal direction of the submarine cable 300.

After the submarine cable 300 is primarily surrounded by the plurality of waste tires 400, the plurality of waste tires 400 are secondarily surrounded by the plurality of the fixing members 500. There is no limitation on the form in which the plurality of fixing members 500 surround the plurality of waste tires 400. However, in a preferred embodiment, a plurality of the fixing members 500 are provided so that the plurality of waste tires 400 are not directly exposed to the sea 100 500 are covered on a plurality of waste tires 400 so as to be extended along the longitudinal direction of the submarine cable 300. In the case of the waste tire 400, although it has an advantage of more effective shock absorption than a metal material, there is a problem that it is light in weight. The waste tire 400 protecting the submarine cable 300 is liable to be lost due to light or wave due to lightness. Therefore, the construction for covering the fixing member 500 on the waste tire 400 is carried out in order to prevent the waste tire 400 from being drained and to protect the submarine cable 300 more stably.

At this time, the fixing member 500 preferably has a larger unit volume weight than the waste tire 400. The weight per unit volume refers to the weight per cubic meter, which is a unit used to compare relative weights between two objects. It is possible to prevent the waste tire 400 from being lost due to the weight of the fixing member 500 being larger than the weight of the waste tire 400 by a unit volume.

At this time, the fixing member 500 is not limited to a specific material, but is preferably a stone or a waste concrete. Waste concrete refers to materials that have reached the end of their life due to the concrete being used in the construction process. Stone or waste concrete is less expensive than conventional duct metal. This has a great advantage in reducing construction costs. In addition, the stone or waste concrete is heavy, which can more effectively prevent the waste tire 400 from being lost.

Fig. 4 is a plan view showing an embodiment of a plurality of waste tire-to-tire joining methods. Hereinafter, an embodiment of a method of joining waste tires according to the present invention will be described with reference to FIG.

In the construction process of covering the plurality of waste tires 400 to the submarine cable 300, the connection between the waste tires is necessary to prevent the separation of the plurality of waste tires 400. At this time, coupling through the chain 600 is possible to an embodiment 410 of a method of joining a plurality of waste tires 400. The chain 600 may be formed in a zigzag shape in a zigzag fashion on the basis of the hole 401 formed in the plurality of waste tires 400. In this case, 401) so as to connect the plurality of waste tires 400 to each other. Due to the combination of the chain 600 type, it is possible to protect the submarine cable 300 by using the waste tire 400 more firmly.

It is also possible to connect the waste tire 400 by binding the chain 600 along the periphery of the plurality of waste tires 400. At this time, it is also possible to cover the entire submarine cable 300 by connecting the unit members in the width direction of each of the waste tires 400, which are bound to the chain 600, along the longitudinal direction of the submarine cable 300.

5 is a plan view showing another embodiment of a method for joining a plurality of waste tires according to the present invention. Hereinafter, another embodiment of the method of joining waste tires according to the present invention will be described with reference to FIG.

Unlike an embodiment 410 of a plurality of waste tire 400 coupling schemes through chain 600 described with reference to FIG. 4, another embodiment 420 includes a plurality of waste tire (s) 400). A plurality of waste tires 400 are inserted into the net 700 to form the mattress 800 and the submarine cable 300 is covered with the plurality of mattresses 800 to protect the submarine cable 300. The mattress 800 refers to a plurality of combined bodies of waste tires 400 fixed by a net 700 and is connected to a plurality of waste tires 400 through a bag capable of holding the waste tires 400, (400) is also referred to as a mattress (800).

6 is a front view showing a stacked state of a plurality of waste tires according to the present invention. Hereinafter, a plurality of combined waste tires stacked together will be described with reference to FIG.

It is also possible to vertically stack the waste tire 400 on the submarine cable 300 after a plurality of waste tires 400 are combined according to the embodiment 410 or the other embodiment 420. [ When the waste tire 400 is stacked in the vertical direction, the surface area of the waste tire 400 is increased, and the probability of the submarine cable 300 being broken from the anchor, the horseshoe and the fishing gear is lowered. In addition, since the total height of the waste tire 400 can be changed through the lamination, the size of the submarine cable 300 can be tailored to the anchor, The position of the waste tire 300 can be adjusted. Thereby, there is an advantage that the submarine cable 300 can be protected more effectively.

While the present invention has been described with reference to the particular embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
